Latent semantic indexing

Overview of the Semantic Gap - What is it? The semantic gap is the difference between human perception of observations, activities, and objects and their computational or machine-based representations(). It is a split between high level features, or semantic information, and low-level features, of which there are many types. High-level features can include keywords, concepts, categories, or ontologies - virtually all things that lead to determining meanings of text-based information and phrases. Low-level features can include color, texture, resolution, encoding, salient points, etc. which are all measurable aspects of content-based information, or non-text information, such as images and videos. The spread of multimedia on the web is widening…

synonymous relation phrases. Relation vector based clustering: Follow the traditional principle for such task, we run k-means clustering method on relation phrases represented by relation vectors. Relation vector is basically a bag-of-words model, which contains TF-IDF values multiply occurrence frequency for each term. In addition, we observe that the meaning of relation phrase becomes ambiguous without considering entity type information. For example, “prevent” and “treat” are similar…

bigger than those with lower batting averages. This reflects on the idea of embodied cognition because performance of the athletes depended on their perceptual system to improve their motor functions; in this case they would be able to swing the ball much more frequently. Glenberg decides it is time to consider that the perceptual system as part of an integrated perception-action system (Glenberg, 2013, 7). This consideration can be supported through replication of Witt’s experiment, but using…
